Did that. Found that all except the Mathematica plugin directory had only 
permission bits 440 as root.root instead of root.user (which explains the 
permission problems). To fix this, I issued :

/usr/local/share/TeXmacs/plugins# chmod -R +r */progs

This gets rid of the startup permission problems and restores a lot of the 
missing Sessions, but starting Mathematica still fails due to a permission 
problem :

gcc -o /home/m_singh/.TeXmacs/bin/tm_mathematica.bin 
src.lazy/tm_mathematica.c -I 
/usr/local/Wolfram/Mathematica/5.0/AddOns/MathLink/DeveloperKit/Linux/CompilerAdditions
 -L 
/usr/local/Wolfram/Mathematica/5.0/AddOns/MathLink/DeveloperKit/Linux/CompilerAdditions
 -lML
Error in Mathematica plugin installation
cc1: error: src.lazy/tm_mathematica.c: Permission denied
make: *** [/home/m_singh/.TeXmacs/bin/tm_mathematica.bin] Error 1
mathematica]

Now, I realized that files under src.lazy in each of these plugins were also 
set to 440 bits. Added the read permission (never had to do this - shouldn't 
the files be installed as belonging to root.user instead of root.root as they 
are ?). Now, Mathematica seems to load :

gcc -o /home/m_singh/.TeXmacs/bin/tm_mathematica.bin 
src.lazy/tm_mathematica.c -I 
/usr/local/Wolfram/Mathematica/5.0/AddOns/MathLink/DeveloperKit/Linux/CompilerAdditions
 -L 
/usr/local/Wolfram/Mathematica/5.0/AddOns/MathLink/DeveloperKit/Linux/CompilerAdditions
 -lML

Thanks for the help. Wonder if the improper install is a bug in the CVS 
version.
